Thank you, Kirin, and good afternoon, everyone. I'm excited to share the results from our third quarter 2025, a period that marks another step forward in Nephros' transformation and growth story. We delivered $4.8 million in revenue, our second highest quarter ever, and we did it with strong contributions across our business. This past quarter also marks our fifth consecutive quarter of profitability, and I'm so excited to report that we reached the highest level of programmatic business in our company's history, a milestone that reflects the consistency, the resilience and increasing value of our recurring revenue streams. What's driving that? Well, our filtration installation program continues to be a powerful growth lever. We've seen that when we support our customers with the full installation experience, not just the product, reorder rates go up, engagement deepens and customer loyalty strengthens. That's not just good for the quarter. That's good for long-term business. Another exciting development, our PFAS, PFAS removal solution is now in the field. This breakthrough opens the door to new verticals beyond our traditional patient care markets, including municipalities, dialysis centers and labs as much more attention is being paid to this alarming issue. While early, the response has been encouraging, and we believe that this will be a growth engine for years to come. We've also deepened our commercial traction in cross-functional coordination. Our teams are firing on all cylinders, and our sales force continues to bring in high-quality opportunities, not just more business, but the right kind of business. As we expand into dental, municipal and government facilities, we're doing so with operational discipline and strategic focus. As I look ahead, I'm incredibly optimistic with strong customer retention, a record number of active sites and new innovations already in the market, we're executing extremely well today and building momentum for tomorrow. Our intense focus and financial discipline is clearly driving our revenue growth and profitability. With our strong balance sheet, 0 debt and the robust innovation pipeline, we remain confident that Nephros is well positioned to sustain growth, broaden our market reach and deliver strong value in the quarters ahead. Thank you to our employees, our partners and investors for your continued belief in Nephros. With that, I'll turn it over to Judy for a more detailed look at our financials. Judy?

Thanks, Robert. I will now provide a closer look at Nephros' financial performance in the third quarter and year-to-date of 2025. We reported third quarter net revenue of $4.8 million, a 35% increase over the corresponding period in 2024, reflecting strong growth in our programmatic business and significant growth in our service revenue. Our active customer sites continued to grow sequentially and were over 1,650 as of September 30, 2025. Gross margins in the quarter came in at 61%, which is consistent with 61% in the third quarter of 2024, which reflects an increase in inventory handling expenses, including tariffs that were mostly offset by a reduction in inventory reserve adjustments. Research and development expenses in the quarter were $338,000 compared to $188,000 for the same quarter in 2024. Expenses were higher in 2025 due to higher accrual for employee bonuses and an increase in headcount. Sales, general and administrative expenses in the quarter were $2.2 million compared to $1.7 million for the corresponding period in 2024, an increase of 30% due to higher sales commissions resulting from increased revenue and higher accrual of employee bonuses. We are pleased to report a significant increase in net income for the quarter. We ended up with $337,000 compared to $183,000 in the same period last year. This marks our fifth consecutive quarter of profitability. Adjusted EBITDA in the quarter was positive $418,000 compared to $295,000 during the same period in 2024. Net cash provided by operating activities was $99,000 in the third quarter of 2025 versus net cash used of $623,000 in the prior year period, an improvement of $722,000. Net cash provided in the third quarter of 2025 reflects primarily our positive net income, offset by an increase in accounts receivable. Net cash used in the third quarter of 2024 reflects…

Thank you, Judy. As we look to the future, our focus remains clear: scale what's working, pursue what's next and stay grounded in our mission. The progress we've made across operations, our commercial strategy and financial performance has laid a strong foundation for sustainable growth. In a world where water quality and infection control are increasingly vital, Nephros is well positioned to lead. This quarter has shown what's possible when innovation meets execution and purpose drives performance. We are energized by this momentum, and we're not only at the beginning of what we believe is a long runway. It's a point where the future is up for us. At this point, we'd like to open this up for questions. Operator?

[Operator Instructions] The first question comes from Thomas McGovern with Maxim Group.

Congrats on another strong quarter here. I just wanted to see if we could dive in a little bit more into the new PFAS filtration solution that you guys launched back in October. So it sounds like it kind of broadens your potential market into those municipalities and some, I guess, more rigorous regulatory environments like dialysis and other labs. But maybe just kind of unpack for me just what the significance really is as we look at how it could impact revenues in '26 and in the fourth quarter.

Great question, and great to hear from you again. Thank you for your support and continuing to dial in. So PFAS, what that does is gives us another opportunity to meet the needs of our customer. Often, we get hit with the most challenging situations. Typically, it's pathogen-based. And more frequently now, we're being asked about what do you have to remediate against PFAS. And in addition, we're also being asked about microplastics and nanoplastics. So an effort to meet the needs of our customers instead of turning them away to maybe potentially one of our competitors, we introduced this PFAS as an option. And what I've also noticed is it's not typically the same customer that you find in a patient care or hospital setting that is concerned about PFAS. PFAS tends to be a more longer-term impact and have implications over some broader period of time. So we're getting closer to more of the commercial and sometimes even high-end residential people that are asking us these questions. So the -- what we have to do at Nephros is figure out how do we turn that opportunity into something that we can make commercialable and not do what we're doing with the infection control part of our business. So I love how this is giving us this ability to look into other areas, other markets and have an opportunity to educate those who are reaching out to us about all the different hazards that they're going to find in water. So we see this more as a conjunction or even a door opener for lead-in to some of our other technology that we've been growing our core with. So in those regards, PFAS is a door opener. It's also branching out into new markets and giving us a chance to have a new conversation with somebody who wasn't always curious about viruses endotoxins and bacteria in the past. So that's pretty exciting for us. And what that means as far as growth is still to be seen as we're just now getting started and launching and exploring how we treat new customers with that technology. Hopefully, that answers the question.

Yes, absolutely. I really appreciate that insight. So when we kind of take a step back and look at the PFAS versus some of the other innovations you've launched recently, being the -- whether it's the S100 or the UltraFilter, all of those are pretty early stage in terms of how long they've been commercially available. But could you give us somewhat of an idea as to what you see as the largest driver of growth at least in the near term in 2026, then maybe taking a step further back and looking at this as what's the largest opportunity for you guys on the whole as you guys look at your business long term?

That's a good question. The strategy has always been and will be to grow the core and make sure that the items that we're most differentiated at, that's our [indiscernible], sorry, our infection control product line. And where I see the new products that were launched like the HydraGuard or even the -- all the other items that will address ST108, what that's doing is allowing us to meet some of the needs specified in ST108 and other regulations that hospitals are working with today. So those are pretty stringent, and they're asking our customers to do more and more, test more and be able to have mediation against endotoxins, some of the most difficult pathogen particles to remove. And that's what's driving a lot of our growth today. Customers are trying to understand what that means, how to create water management safety programs around those regulations and what products they might need to do in order to make sure that they're compliant. And the good part about that is we're very well educated on how to do that. We've got experts that are willing to talk. And it doesn't always mean that they're going to buy more Nephros filters. They may have to install more testing tasks, for example, or change the order of their equipment or how they maintain their equipment. Just the fact that we're there educating them on how to meet some of these guidelines usually means that they turn to us for other solutions and filtration needs as well. The philosophy I like to think about is an educated customer is a Nephros customer. The more we can teach them about how to meet their water needs and handle some of these more challenging environments, the more likely they are to not turn to a competitor who has technology that may not be able to do what they're trying to do and towards a Nephros product, which is able to handle the most tough conditions.

Understood. You also mentioned in your prepared remarks that you guys have a robust innovation pipeline. Just curious if there's anything we should be keeping our eye out as we kind of enter the end of the year and enter '26 as well.

Our innovation pipeline is pretty robust. We always have more that we want to do than we have time or bodies to be able to do. So we typically will pivot to try to meet whatever newest challenges are out today and what we see coming in the future. And today, the challenges such as forever chemicals, PFAS and more towards the future a bit, the microplastics, nanoplastics, I think those are going to be products that we see our pipeline meeting and satisfying that will drive more growth in the future. And why do I think that? It's because those situations, especially nanoplastics, are very difficult. The size of those particulates and the harms they can do by penetrating the blood-brain barrier and causing cellular disruption and endocrine disruptions, it's a really challenging situation. And as that becomes more and more known and more and more prevalent, there are not solutions out there today that can easily handle it. And I think we're well positioned to deploy our technology to be able to remove those nanoplastics. So you'll see innovation and products released and announcements around meeting some of those really tough challenging questions that are coming in the future.

I was muted there. Understood. I appreciate that. I'll have one more and then I'll hop back in the queue. You guys did call out specifically the filter and installation program is continuing to support growth in programmatic business, which is great to see. One thing that I didn't hear on the call was comments on the tracking app. I just wanted to see if we could get an update on that. And maybe if you could break out, as you see it at least, kind of this record programmatic sales, how much of that -- you have to get super specific, but just kind of high level, how much of that growth in programmatic business do you think is attributable to this filter installation program versus the tracking app itself?

Yes. No, great question. Tracking app is doing well and continues to grow. We've expanded not as much in the amount of sites that we're tracking, but more in the geographies that we're tracking. Now we've got key installations in Texas and California, Florida, New York. So the biggest markets, and we're still looking to penetrate the Midwest a bit more. But this tracking app is doing a couple of things for us. Number one, it's allowing us a tool to give the customer more value. They can see the installation, have a picture of what was installed, how it was installed, when it was installed, who did the installation. They can also see -- get the messages and reminders that it's time to change it. And I think that's the most important powerful part on our side as far as getting those repeat customers. But in addition, it's allowing us to create more touch points. And now the touch point is that we are out there doing the install in sight. And while the technician might be walking to install something at a sink, he sees a water fountain that might be offline since COVID, like, oh, by the way, we have a solution that can get that fountain back online. have you guys heard about the new install processing guidelines? Do you have any instrument washing on site? So those discussions that don't necessarily show up in the service revenue are -- do show up in core programmatic growth and allow us to expand within those existing sites. And that's what's got me most excited about the installation program. It's that dialogue and those touch points and yet another opportunity to educate the customer about how they can meet those water needs and satisfy the challenging environments that they face, especially with some of the new regulatory guidelines out today.

Our next question comes from Ralph Weil with R. Weil Investment Management.

You talked about PFASs and you've talked about microplastics. And hopefully, you will have solutions for both of them. And I'm just wondering whether you are going to be doing this and trying to enter these businesses on your own through your distributors or with joint ventures or partnerships with people who are already -- or companies, I should say, who are already in the field and where you could work with them or they could work with you at penetrating the market with your new products. That's one thing. And the second question I have at this point is there's been a tremendous amount of publicity about Legionella disease. And I'm wondering whether that has had an effect on your quarter and also whether the government realizing that this is a significant problem with the old water pipes and thinks, et cetera, et cetera, that the government regulations, whether they be the word we've heard in the past so many times, ASHRAE or any others, whether they will be more stringently enforced and thus become more meaningful to you going forward?

Rob, thanks for joining, and thanks for the 2 questions. And I'll answer the first one about penetrating the markets, and then we'll touch on Legionella after that. And if I don't answer any of them clearly or completely, just please ask more. So how will we penetrate the market? When we look at new technologies such as PFAS, and I mentioned this initially that it's not always the same customer that we're talking to today. So penetrating the market is a good question and a key one that we think about. At the end of the day, we sell our products to the market directly and through distribution. And that is -- those are the 2 channels that we'll continue to enter the market with. And one of the things that we're figuring out is do we have the right partners to talk about PFAS? Do we have the right internal arrangement in order to answer the questions and calls that might come in from organizations that are not the typical hospital networks. And that's the question we answer and look at every day. And we are having to change our model slightly. We're actively pursuing it. But what we find is that at the end of the day, it's still our salespeople are experts internally that end up explaining how their remediation is done. They're still the ones, whether it's through an introduction to a distributor or whether it's through a direct phone call or on marketing leads or a trade show, they still are the ones that are explaining the solution, giving the quote and helping the customer through that solution as they work to remediate that problem. So we're excited about the new opportunity. We're excited about the new audiences that it brings us to and…

Can I ask one other thing?

Absolutely.

In the 10-Q, you talked about besides the hospital business, you talk about other newer areas where the filters are being deployed, such as laboratories, manufacturing facilities, aviation environments and government buildings. Can you elaborate a little more where you have made inroads and which of these you see could be a bigger market for the company? Obviously, not as big as hospitals, but where you can really grow them in a nice way.

Yes. So I'd love to share names and locations, but we -- our customers often don't want that information out there. But I often am seeing now where people that share the characteristics of patient care facilities when their populations have those same characteristics, they're often very strong candidates for our solution because you're looking at a market segment that shares a similar buying criteria. They may have populations at risk or elderly, younger immune compromised or they may have high-end populations of people just concerned about getting sick at all. But people in close proximity, people that have to share space, share appliances such as bathroom fixtures and shower fixtures, those are all opportunities. So think about correctional facilities, maybe schools, municipal buildings, and the like. So those are places where we are seeing deployment. And it's been that way, not just this quarter, but that's been a trend over the past 3 quarters or more, especially as the team goes out and focuses on more than just the 8,000 or 9,000 or so hospitals that are out there. Hospitals are still and will always be a very strong market for us because they are driven by some of the guidelines and even regulations and sometimes accreditations. So they're driven not just by desire for remediating the problems, but also the potential for losing business in customers and patients. So it's been -- I'm not sure if that answered the question, but those are really some of the other places we're looking and reaching out and it's been successful and a major driver for us, especially these past 3, 4 quarters or so.

We have a follow-up question from Tom McGovern with Maxim Group.

I just wanted to hop back in queue to ask about the margins. So you guys explained it. I know you guys source a lot of your components or maybe not a lot, but some of your components, at least from Italy. It seems like tariffs have had somewhat of an impact. Just as we look at the fourth quarter and '26, should we expect this kind of -- you guys were operating around 63% gross margin, this closer to 61%, kind of more in line with some historicals. Is this a better run rate for us as we look forward? Or do you think that there will be some things that will alleviate some of the pressures you're seeing now on margin?

Thanks for the question. Good question. So the impact of tariffs, tariff is an expense as we get inventory in stock, it's capitalized as we sell through the inventory, it affects the cost of goods sold. So as tariff impact has started to increase, obviously, we do source a lot of our filters from Italy. It has an impact as we sell through that inventory. So you certainly started to see some of that. Do we see a full quarter of it that quarter? Will we see a full quarter of it this quarter? It's too close to tell, but I don't think it will have too much more of an impact, but it's a part of our life. So what else affects our gross margin certainly is price increases, and we put through a price increase earlier this year. And so if we do put through another price increase next year, that's something that can offset it. We're managing our inventory very carefully and cleanly. Our reserves are very clean. It's also the mix of business. Certain customers get volume discounts. And depending each quarter on how the mix of business comes in, that affects the margins. So we don't expect a dramatic decrease in margins from the tariffs, but it's a reality. It did have a small impact. We still hope to maintain 60-plus gross margins that will just move around a bit to bit. We're not going to make any projections, but I think it's mostly manageable.

Understood. And last, just a clarifying question real quick. So when you talk about service revenue, that's just really pertaining to this the installation program that you guys have when you go and actually outfit the facility in exchange or replace filters that type of thing? Or is there anything else that's falling into that bucket?

The service revenue refers to -- when we're going in, there's 2 types for us. There's the initial installation where the customer may be either using a competitor's filter or no filter at all. In those cases, we would often put these quick connect fittings and make it so it's a properly installed scenario, maybe it's some manifolds as well. So there's that initial install, it tend to take a little bit longer. And there's also just the regular replacement business where after 3 months, after 6 months, whatever the filter expiration or the rated life of it might be, we would go in and change out that filter as well. So that service revenue refers to those activities that are charged and billed under either contract or onetime services with that customer for performing those tasks.

Understood. I appreciate you guys taking the time. Congrats again on the quarter and looking forward to seeing what you guys can do moving forward.

Our next question comes from Nick Farwell with Arbor Group.

Robert, Judy, thank you very much for a very strong quarter. I'm curious on 2 questions. One is, can you talk a little bit about the trade-off between trying to maximize margins and get -- capture higher incremental margins by managing SG&A? Or are you still in a mode where you feel incremental dollars spent in SG&A are more valuable than incremental profitability?

I'll jump in there first and let Robert add anything additional. We very much have enjoyed this year profitability, EBITDA positive. It feels good. It's a good place to be. We certainly know that we are under-resourced in many areas. There's always room to add more resources in a small growing company, and we have departments that would like more resources. So we do want to manage it carefully. Obviously, we are continuing to add valuable sales resources. In fact, we'll have another one coming on sort of an inside salesperson supporting further our Western region. It's been a great fit, and we think the return is significantly there. But we do want to manage for profitability. We do think it's important. So we weigh opportunities carefully. and we want to be able to support the growth, too, from the warehouse perspective, from the quality perspective. So we're very carefully adding resources as we need them. But I do think it's important to try and maintain fiscal discipline as we continue to grow the company. And again, Robert, if you have more that you'd like to add, please jump in.

Yes. Absolutely, absolutely. When I think about SG&A and adding costs, whether it be headcount, vehicles, anything, it's still guided by the same principle I always have. If it makes sense and I can show a return for that investment that's reasonable and favorable, then I'll do it. If it means adding more people where necessary. But basically, we tested a model a couple of years ago with these associates working under the regional sales managers. And they basically were able to free up our experts to give them time to go out and talk and educate and cultivate and grow these new sales while the associates were cultivating the existing accounts. Super happy with the way that turned out, and we're double, tripling and quadrupling down on that model which will add cost, but it is more than offsetting those costs with the amount of revenue and profits being generated.

And a little add-on question to that is, how have you changed your go-to-market strategy as you address new market verticals, are there different ways you can go to market that you can leverage your SG&A organization, sales organization?

Yes, absolutely. The one we just described is the most different, where we are no longer focused on head down in hospitals, but gotten out to even well beyond patient care areas into other different verticals by doing that. And it's using both direct and indirect channels. But in addition, it's trying to meet those decision-makers where they are. And by understanding who is making the buying decision, learn why they're making that decision and then focusing on potential objections to them choosing Nephros as their solution. Has really put us and led us to different types of solutions. That's why you'll see us taking a number of different paths and ways to make touch points with the customers. We've been attending more trade shows and more talking engagement, seeking engagements this year, and that's paid off as well by getting the Nephros name and solutions out there and matching up those solutions with our technology has been a winning formula for us.

There are no more questions. I would like to turn the conference back over to Robert Banks for any closing remarks.

Thank you. Thank you. Great, great robust question-and-answer session today. I really enjoyed the questions where you're asking about how we're growing. And really when we're scaling and getting more speaking engagements and going to more of these conferences and hosting webinars, here's a plug for our LinkedIn page. You can go there and check out some of those speaking opportunities. It's really helping us to go beyond even individual hospitals and get more to the networks, get more to people to help them build their safety management plans. And I wanted to thank our exceptional team, our dedicated customers and our shareholders. You guys have been very supportive. And as always, if you have any questions, please feel free to reach out to us directly. With that, I'd like to wish you all a great day, great evening.

The conference has now concluded. Thank you for attending today's presentation. You may now disconnect.
